SQLITE_TABLE(5)						       SQLITE_TABLE(5)

NAME
       sqlite_table - Postfix SQLite configuration

SYNOPSIS
       postmap -q "string" sqlite:$config_directory/filename

       postmap -q - sqlite:$config_directory/filename <inputfile

DESCRIPTION
       The  Postfix  mail system uses optional tables for address rewriting or
       mail routing. These tables are usually in dbm or db format.

       Alternatively, lookup tables can be specified as SQLite databases.   In
       order  to use SQLite lookups, define an SQLite source as a lookup table
       in main.cf, for example:
	   alias_maps = sqlite:/etc/sqlite-aliases.cf

       The file /usr/local/etc/postfix/sqlite-aliases.cf has the  same	format
       as  the	Postfix main.cf file, and can specify the parameters described
       below.

BACKWARDS COMPATIBILITY
       For compatibility with other Postfix lookup tables,  SQLite  parameters
       can also be defined in main.cf.	In order to do that, specify as SQLite
       source a name that doesn't begin with a slash or	 a  dot.   The	SQLite
       parameters  will then be accessible as the name you've given the source
       in its definition, an underscore, and the name of the  parameter.   For
       example,	 if the map is specified as "sqlite:sqlitename", the parameter
       "query" below would be defined in main.cf as "sqlitename_query".

       Normally, the SQL query is  specified  via  a  single  query  parameter
       (described in more detail below).  When this parameter is not specified
       in the map definition, Postfix reverts to an older interface, with  the
       SQL  query  constructed	from  the select_field, table, where_field and
       additional_conditions parameters.  The old interface will be  gradually
       phased out. To migrate to the new interface set:

	   query = SELECT [select_field]
	       FROM [table]
	       WHERE [where_field] = '%s'
		   [additional_conditions]

       Insert the value, not the name, of each legacy parameter. Note that the
       additional_conditions parameter is optional  and	 if  not  empty,  will
       always start with AND.

LIST MEMBERSHIP
       When  using  SQL	 to  store  lists such as $mynetworks, $mydestination,
       $relay_domains, $local_recipient_maps, etc., it is important to	under‐
       stand that the table must store each list member as a separate key. The
       table lookup verifies the *existence* of the key.  See  "Postfix	 lists
       versus tables" in the DATABASE_README document for a discussion.

       Do  NOT create tables that return the full list of domains in $mydesti‐
       nation or $relay_domains etc., or IP addresses in $mynetworks.

       DO create tables with each matching item as a key and with an arbitrary
       value.  With  SQL databases it is not uncommon to return the key itself
       or a constant value.

SQLITE PARAMETERS
       dbpath The SQLite database file location. Example:
		  dbpath = customer_database

       query  The SQL query template used to search the database, where %s  is
	      a substitute for the address Postfix is trying to resolve, e.g.
		  query = SELECT replacement FROM aliases WHERE mailbox = '%s'

	      This parameter supports the following '%' expansions:

	      %%     This is replaced by a literal '%' character.

	      %s     This  is  replaced by the input key.  SQL quoting is used
		     to make sure that the input key does not  add  unexpected
		     metacharacters.

	      %u     When the input key is an address of the form user@domain,
		     %u is replaced by	the  SQL  quoted  local	 part  of  the
		     address.	Otherwise, %u is replaced by the entire search
		     string.  If the localpart is empty,  the  query  is  sup‐
		     pressed and returns no results.

	      %d     When the input key is an address of the form user@domain,
		     %d is replaced by the  SQL	 quoted	 domain	 part  of  the
		     address.	Otherwise, the query is suppressed and returns
		     no results.

	      %[SUD] The upper-case equivalents of the above expansions behave
		     in	 the  query  parameter identically to their lower-case
		     counter-parts.  With  the	result_format  parameter  (see
		     below),  they expand the input key rather than the result
		     value.

	      %[1-9] The patterns %1, %2, ... %9 are replaced  by  the	corre‐
		     sponding  most  significant  component of the input key's
		     domain. If the input key is  user@mail.example.com,  then
		     %1 is com, %2 is example and %3 is mail. If the input key
		     is unqualified or does not have enough domain  components
		     to	 satisfy all the specified patterns, the query is sup‐
		     pressed and returns no results.

	      The domain parameter described below limits the  input  keys  to
	      addresses in matching domains. When the domain parameter is non-
	      empty, SQL queries for unqualified  addresses  or	 addresses  in
	      non-matching domains are suppressed and return no results.

	      This  parameter is available with Postfix 2.2. In prior releases
	      the  SQL	query  was  built  from	  the	separate   parameters:
	      select_field,  table, where_field and additional_conditions. The
	      mapping from the old parameters to the equivalent query is:

		  SELECT [select_field]
		  FROM [table]
		  WHERE [where_field] = '%s'
			[additional_conditions]

	      The '%s' in the WHERE  clause  expands  to  the  escaped	search
	      string.	With  Postfix  2.2 these legacy parameters are used if
	      the query parameter is not specified.

	      NOTE: DO NOT put quotes around the query parameter.

       result_format (default: %s)
	      Format template applied to result attributes. Most commonly used
	      to  append  (or prepend) text to the result. This parameter sup‐
	      ports the following '%' expansions:

	      %%     This is replaced by a literal '%' character.

	      %s     This is replaced by the value of  the  result  attribute.
		     When result is empty it is skipped.

	      %u     When the result attribute value is an address of the form
		     user@domain, %u is replaced by  the  local	 part  of  the
		     address.  When  the  result  has an empty localpart it is
		     skipped.

	      %d     When a result attribute value is an address of  the  form
		     user@domain,  %d  is  replaced  by the domain part of the
		     attribute value. When the result  is  unqualified	it  is
		     skipped.

	      %[SUD1-9]
		     The  upper-case  and decimal digit expansions interpolate
		     the parts of the input key rather than the result.	 Their
		     behavior  is  identical to that described with query, and
		     in fact because  the  input  key  is  known  in  advance,
		     queries  whose  key  does not contain all the information
		     specified in  the	result	template  are  suppressed  and
		     return no results.

	      For example, using "result_format = smtp:[%s]" allows one to use
	      a mailHost attribute as the basis of a transport(5) table. After
	      applying	the result format, multiple values are concatenated as
	      comma  separated	strings.  The  expansion_limit	and  parameter
	      explained	 below	allows one to restrict the number of values in
	      the result, which is especially useful for maps that must return
	      at most one value.

	      The  default value %s specifies that each result value should be
	      used as is.

	      This parameter is available with Postfix 2.2 and later.

	      NOTE: DO NOT put quotes around the result format!

       domain (default: no domain list)
	      This is a list of domain names, paths to files, or dictionaries.
	      When  specified,	only  fully qualified search keys with a *non-
	      empty* localpart and a matching domain are eligible for  lookup:
	      'user'  lookups,	bare  domain lookups and "@domain" lookups are
	      not performed. This can significantly reduce the query  load  on
	      the SQLite server.
		  domain = postfix.org, hash:$config_directory/searchdomains

	      It  is best not to use SQL to store the domains eligible for SQL
	      lookups.

	      This parameter is available with Postfix 2.2 and later.

	      NOTE: DO NOT define this parameter for local(8) aliases, because
	      the input keys are always unqualified.

       expansion_limit (default: 0)
	      A	 limit	on  the total number of result elements returned (as a
	      comma separated list) by a lookup against the map.  A setting of
	      zero  disables the limit. Lookups fail with a temporary error if
	      the limit is exceeded.  Setting the  limit  to  1	 ensures  that
	      lookups do not return multiple values.

OBSOLETE QUERY INTERFACE
       This  section  describes	 an interface that is deprecated as of Postfix
       2.2. It is replaced by  the  more  general  query  interface  described
       above.	If  the	 query	parameter  is  defined,	 the legacy parameters
       described here ignored.	Please migrate to the  new  interface  as  the
       legacy interface may be removed in a future release.

       The  following  parameters  can	be  used  to fill in a SELECT template
       statement of the form:

	   SELECT [select_field]
	   FROM [table]
	   WHERE [where_field] = '%s'
		 [additional_conditions]

       The specifier %s is replaced by the search string, and is escaped so if
       it  contains single quotes or other odd characters, it will not cause a
       parse error, or worse, a security problem.

       select_field
	      The SQL "select" parameter. Example:
		  select_field = forw_addr

       table  The SQL "select .. from" table name. Example:
		  table = mxaliases

       where_field
	      The SQL "select .. where" parameter. Example:
		  where_field = alias

       additional_conditions
	      Additional conditions to the SQL query. Example:
		  additional_conditions = AND status = 'paid'
